To all whom it'mayconcern:

Be it known that I, VIRGIL W. BLANCH- ARD, of New York, in the county of New York and State ofNew York, have invented certain new and-useful Improvements in Cooking-Ovens; and I hereby declare that the following isa full, clear, and exact description thereof, reference being had to the accompanying drawings,-which form part of this specification.

This invention is an improvement in cookmg-ovens, especlally designed for gaseous -fuel-burning-stoves, and more particularly is designed for use in ranges of large capacity.

The object of the present. invention is to provide an oven which can be located above the heat-generatingportion ofthe apparatus and heated by means of the hot gases sup-- plied directly therefrom at the will of the operator and to construct this oven with a plurality of heating-chambers in each of which heated gases may be directly admitted when desired to have the same very hot, as when cooking operations are being performed therein, and which also can be indirectlyiheated by heat supplied from adjacent chambers and by an internal heating-chamber.

By this apparatus articles requiring different temperatures for cooking can be simultaneously cooked in the different compartments of the oven, if desired, or one or more of the compartments can be used for warming-ovens, while others are used for baking pur oses, and whenused in large ranges the che operating upon any one of the cookingranges of the apparatus can have convenient access to one of the compartments .of the oven adjacent to such range and use the same for cooking operations without interfering with or being interfered with by other chefs cooking on the other range portions of the apparatus.-

The device will be fully understood from the following description and the accompanying drawings, in which- Figure 1 is a part side elevation and part section of the complete oven as appliedv to one of my cooking-ranges, and Fig. 2 is a top plan view of the oven.

n the drawings the gas-burning cookingrange shown is preferably constructed with a central ortion S, in which the heated gases are pro need, and a series of horizontally-arranged range-sections s, which communicate with the upper part of stove S and preferably radiate indifferent directions, so that a series of these ranges can be-heated from the one generating apparatus, and preferably the heat may be directed into any of the. range portions by means of valves s The burner not shown) gases into a hood D, above which are a series of alternating plates E and E, by-which the hot gases are constrained to move inwardly and outwardly as they rise above the dome and are thoroughly oxidized, said domeand plates forming a highly-heated mass of metal in the center'of the stove andinsuring the thorough combustion of all the gases.

In the-top of stove 8- above the'burner are a series of opemngs a, which may be covered discharges thehot by suitable lids when the heating-oven, here'- v inafter described, is not in position. 1

The partsthus far described maybe of any preferred construction and are not essential features of the present invention.

Above the stove is arranged a heatingoven, which, as shown, is preferably cylin drical in shape and is divided into a series of compartments, one for each range extensionof thestove, and, as shown, there are four such compartments 1 1 1 1, to which access can be had from the exterior of the oven through openings in the sides thereof, closed by doors 2 2 2 2. Preferably the doors 2 2 2 2 are interiorly lined with non-heat-conducting packing like the exterior walls of the oven, so

as to retain as much heat as possible within the oven. Y

I preferably also form within the oven a closed compartment 1, that may be formed by-a metal casing 3, which, as shown, is rectangular in cross-section and from which casing radiate partitions 3 3 3 3, which divide the remaining space in the oven into the compartments 1 1 1 1.

Preferably the outer walls of the oven are composed of outer layers 1 and inner layers 1 the space between said layers being filled with non-heat-conducting material 1 so as to prevent loss of heat'by radiation or conduction. The bottom and top walls of the oven may be similarly formed.

The hot ases can be admitted into the lower end of each chamber or compartment 1 1 1 1 1 through pipes 4 4 4 4 4, which connect with o enings a in the top of stove S, as shown. 15 vided with a valve 4 so that the passage of hot gases to each compartment is controllable. These pipes 4 4 4 4 4 form convenient supports to sustain the oven in position upon ach pipe may be proment is an opening closable by a valve 5 5 5 5 5 which can be operated by pull-rods 6 1 6 6 6 6 as indicated in the drawings.

When gases are admitted into any compartment, the upper valve therein may be opened to permit more or less rapid circula tion of heat through the compartment.

-By this construction it is obvious that a chef operating upon any of the range extensions has an oven at hand and can easily regulate the temperature thereof to suit himself, and when it is not desired to use this oven for cooking purposes the inner and outer valves thereto can be closed and the oven kept at a sufiicient temperature by means of the heat radiated from the inner chamber 1 I propose in practice to make the walls of the oven sufiiciently thick to store a large amount of heat therein to enable cooking operations to be performed in the compartments by the accumulated heat instead of by direct heat of the gases. Obviously by means of the valves the temperatures in the several compartments can be regulated and variedto suit the chefs and the character of the food being cooked therein.

Having thus described my invention, Wh at Iclaim as new, and desire to secure by Letters Patent, is

1. In combinationwith a gas heating-stove, an oven above the same provided with a series of radially-arranged compartments, pipes for conducting hot gases from the stove directly into the respective compartments, and valves in said pipes.

2. The combination of a gas heating-stove, an oven above the same provided with a series of radially-arranged compartments, pipes for conducting hot gases from the stove directly into the respective compartments, openings in the up er ends of the compartment, valves for c osing said openings, and doors in the sides of the compartments for admitting access thereto;

In testimony that I claim my own I aflix my two Witnesses.
